The CT Sounds CT1X12 is an empty enclosure for a single 12-inch car subwoofer. It has a kerf-style port, a design usually found in custom enclosures. The 11.34-inch cutout and universal fit work with a wide variety of subwoofer brands. The internal walls are lined with poly-fill.
The box is built from 3/4-inch MDF. Dado joints connect the left and right pieces to the back, top and bottom pieces. Miter joints join the corners at a 45-degree angle. Recessed side panels add to the air-tight, vibration-free construction.
The box is wrapped in black carpet and has a flush-mounted black terminal cup. The cup has 8-gauge push terminals, with red and black stickers marking positive and negative. Inside, 12-gauge speaker wires are pre-soldered to the terminal cup, so the box is plug-and-play.
